Towards a Trusted third party based on Multi-agent systems for automatic control of the quality of service contract in the Cloud Computing

Currently, SLAs assurance forms one of the major challenges for Cloud Computing (CC) in order to guarantee Quality of Service (QoS) in real-time and control SLA violations. Autonomous and flexible agents and Multi-agent systems (MASs) are suitable tools for self-detection of failures and self-monitoring of cloud operations and services, QoS negotiation and SLA management. They're designed to operate in a dynamically changing environment. MASs offer new features such as autonomy, pro-activity, communication, cooperation, and negotiation, which can help cloud computing platforms to offer solutions that aren't available in current cloud infrastructures. Our main motivation to integrating MASs is their ability to make clouds smarter in their interactions. This paper introduces a Trusted third party (TTP) based on Multi-agent systems in order to control the quality of service contract and guarantee transparency and symmetry with respect to the SLA contract between prospective signatories. This TTP will use MASs to apply an advanced penalty model that guarantees the performance and the reliability of the Cloud.
